Embodiment
To describe execution mode in detail now, embodiment shown in the drawings.As much as possible, in whole accompanying drawing, use identical Reference numeral to represent identical or similar parts.
Fig. 2 is the figure of the system layer of IPTV (Internet Protocol Television).
With reference to Fig. 2, the IPTV system comprises Content supply quotient sheaf, service provision quotient sheaf, network provisioning quotient sheaf and consumer's layer.
The effect of content provider is to provide content to the service supplier.
Service supplier's effect is to provide service to the user.And the service supplier collects various contents, and signal is changed to adapt to IP world, carries (deliver) this signal through conversion to the consumer then.In this case, the service supplier can be corresponding to pseudo-entity, and content provider can be the service supplier.
The effect of Network Provider is to connect consumer and service supplier via IP network.
Transportation system can use the diverse network that comprises access network, backbone network etc.The consumer is used to receive the layer that substantial broadcasting is provided.And this consumer comprises TV set-top box (set-top box), personal computer (PC), portable terminal etc.
Describe the notion of IPTV in the following description in detail.
Fig. 3 is the performance plot of IPTV system.
With reference to Fig. 3, the system layer of IPTV mainly is classified as content provider, service supplier and consumer.Content provider is also referred to as platform supplier.Three types group has different effects respectively.
Content provider can represent broadcast program is provided the group of comprehensive service and data.
The service supplier sends multi-medium data.The service supplier provides maintenance and management to realize the stable reception of content to the consumer.In addition, the service supplier provides infrastructure and the function that makes it possible to carry out Network Transmission to content provider.
In addition, the effect of consumer's group is that broadcast utilizes the data of infrastructure (for example, xDSL, cable etc.) input or quick response is made in user's request.The consumer organizes and mainly comprises the manufacturer that is used to make IPTV, and the kind of consumer's group can be divided into IPTV, IP STB, IP phone etc.Below respective sets is elaborated.
At first, content provider's group can comprise the TV station that makes broadcast program.This TV station is meant traditional terrestrial broadcast station or wired broadcast station.The program that these broadcasting stations make and the storage consumer can watch and can carry out digital translation to the program that will send.This makes it possible to realize the transmission of various broadcast types.
Broadcasting station (radio station) is meant common radio broadcasting station, and can have video channel in some cases.Yet mainly work under the situation of no video channel in the broadcasting station.VoD (video request program) or AoD (Audio on Demand) service have the characteristic that is different from TV station or broadcasting station.
Content provider can store and keep the program that will broadcast.Yet this program is to have successional direct broadcast.Therefore, this program is characterised in that if do not write down then can't carry out rewinding or time-out to the content that will watch.
Yet, in the situation of VoD and AoD, can store concrete broadcast program, film or music, play in the time of will seeing afterwards.For example, if owing to not free cause having missed to the watching of current broadcasting program, then visit provides the website of broadcast service to download corresponding file or to play-over downloaded files.Similarly, AoD provides the function of real time record audio program or audio plays program.MoD (Music on Demand) service makes the user can download concrete music to listen.Can expand the target that traditional network service manner realizes the MoD service by diskery or publisher.
Below, the execution mode of the service that provides by content provider's group is described.
At first, all broadcast messages that can be provided by organize content supplier and the company of positional information provide service to the PF server.This service mainly comprises the broadcasting or the airtime desired position information of respective broadcast and is used to make client can visit the information of respective broadcast.Client can obtain and show this information on screen.The PF server is one of mandatory service of each broadcasting station.In the IPTV environment, this service is provided to make client can visit corresponding broadcasting station.
EPG (electronic program guides) service is a kind of of convenient service, provides this facility service so that client can obtain broadcast program and appreciate broadcast program by channel ground by ground, time zone.The EPG service is constructed to carry out in the mode that corresponding program is installed in advance automatically at client's end place.
Client only can obtain the information at respective broadcast station from the PF server.Yet the EPG service makes client can once obtain the information of the real-time broadcasting channel in all broadcasting stations.Therefore, the EPG service is very easy to use.For example, EPG service is provided with to subscribe and records the power that Disney Channel is watched in CNN news or reservation.Therefore, the EPG service should provide the details of the information of broadcast program by ground, time zone in corresponding zone.Specifically, supposing predetermined is drama, searches for the content of this drama.This broadcast program can be classified as SF, drama, animation etc. to distinguish.Can comprise film or the story of drama or personage's details at the simple broadcast program.
Because watch client permission of a great variety of IPTV, a big problem of EPG service is how to send the EPG data that are suitable for client.In order to visit the EPG service, client easily searches and presses the enter key of remote controller.
EPG service having the multiple function of the positional information of using content information that content server had, access server of being used to make things convenient for customers, insertion authority information etc.In brief, this function comprises and is convenient to the function that the electronic program guides (EPG) to the details of the information of the content of server and expression content conducts interviews.
Specifically, be that the mode of a kind of service (as the EPG except that broadcasting in real time) can reduce independent visit predetermined content and serves to watch or to download the workload of content with the service binding that will comprise AoD, MoD and VoD.
With the EPG service class seemingly, ECG (digital content guide) service makes it possible to watch the content of storing in the server at any time, but not notifies real-time broadcast channel information.And the ECG service can realize the download and the storage of content.If client attempts visiting the server with content corresponding, client is difficult to address acquisition or visit PF server.This is very complicated processing and expends the considerable time.Provide the company of ECG to make the ECG program can be installed in the client place automatically, collect the information of various contents, and corresponding data are provided.In order to visit the ECG service, as long as client is also the enter key button on the click remote controller.
The network service that portal server provides via each broadcasting station is connected with the broadcasting station or is connected with the webserver of the company that content service is provided.The effect of portal server is to search for or watches by each broadcasting station or the programme that provides each content provider of content service to provide.This is considered to the function of ECG or EPG.Yet, but portal server also is equipped with the function as authentification of user perhaps contract.Therefore, need visit to watch concrete program.Although ECG or EPG provide unified broadcasting or contents list, portal service provides at corresponding program provides the broadcasting of company or contents list information can carry out detailed search.In order to visit portal service, as long as client is the door load button on the click remote controller.
Therefore, content provider's side should comprise the function that above-mentioned service etc. is provided.If attempt these functions of normal running, then the server of service company should insert IP network with corresponding program of real-time transmission or transmission broadcast message.
And, thereby corresponding broadcasting station or service company should carry out error-free transmission on the network that is connected to the service supplier under the situation that does not have delay.Therefore, they should have the system that the Internet of utilization real-time protocol (RTP) (for example, RTP, RTSP, TSVP, MPLS etc.) comes transmitting multimedia data.
For example, attempt if this multimedia comprises MPEG-2 and AC-3 audio frequency standard, then should carrying out the code conversion work that is used to convert them to the form that is suitable for IPTV under the multimedia situation of real-time Transmission at the current television stadio of news that provides.After the server that is used to carry out this work was passed through, tectonic system promptly added and comprises that the RTP/UDP agreement of the temporal information (time information) that is used to mate captions or dialogue is with the IP network by being provided by the service supplier as follows.
Stability of network and bandwidth are provided the service supplier so that content provider transmitting multimedia data and broadcast data well.The service supplier can utilize traditional cable network that IPTV is provided service.In this case, need the equipment of transmission network be changed.Specifically, should should come configuration network by considering bandwidth for this configuration provides the network equipment and the client that can carry out real-time Data Transmission.Described equipment should be handled a large amount of multi-medium datas to reduce bandwidth as the basic network service of IPTV by using multicast services.If can't guarantee bandwidth, then the service supplier make great efforts to change optics cable network structure or will be from the multi-medium data code conversion of content provider the data of MPEG-4 or MPEG-7 form to guarantee bandwidth, send corresponding data then.For this reason, the service supplier should provide the multiple service that comprises NMS (network management system), DHCP (Dynamic Host Control Protocol) and CDN service.
NMS service can be managed the service supplier to be used for the transmission network that transmits to each client and corresponding client's IPTV receiver.Specifically, because the technical difficulty of transmission network causes client can't obtain the situation of broadcast reception, should be provided for the device of emergency treatment.
NMS is widely used as the standard set-up that the machine that is positioned at the remote transmission layer is controlled and managed.Utilize this service, can detect for scheduled broadcast and produce how many communications or which zone shortage bandwidth.Should provide the NMS service so that content corresponding supplier can generate and the managing multicast group to content provider.Reason may need once in a while to be to produce more a plurality of multicast group.
The DHCP service makes it possible to the automatic distributing IP of client's IPTV receiver, and is used to notify the address of CDN server.The DHCP service is the useful assembly that is used for the PC distributing IP on general network.By sending addressable address to the IPTV receiver of authorizing, the user can carry out registration procedure in maiden visit.As a rule, the IPTV receiver will provide IPv4.Yet IPv6 also is available.Therefore, it also is available providing the IPTV receiver of IPv4.
In CDN service, when the IPTV server being carried out initial operation, when receiving IP, receive CDN information from the service supplier by the DHCP service by the data that receive an authority utilization and provide by the service supplier.This information comprises client's register information or IPTV supplier's authentication information and above-mentioned PF information.Because the IPTV receiver obtains the CDN information from the service supplier, therefore support the reception of IP broadcast signal.
Client can have multiple IPTV receiver.Thereby the client who has common TV rents IPTVSTB and appreciates IPTV with cheap price.The service supplier collects over charge with cheap price and client can ask to use with IP phone.
The IPTV receiver mainly comprises network interface that can accesses network and has Internet protocol.The IPTV receiver receives the packet of automatic network and this packet is handled, then play multimedia data on screen.Utilizing remote controller to control under the situation of IPTV receiver, this IPTV receiver should be by responding to obtain corresponding information from server via the grouping of network FastData.Specifically, the IPTV receiver can be operated when handling multi-medium data to send the project of user's request two-wayly.And, can be provided for the button of IPTV suitably to use corresponding service to remote controller.Therefore, the consumer can store and watch the exquisite scene of the drama that the IPTV receiver that provides above is provided, and enjoys the Additional Services that comprise positional information, hotel reservation etc.
Simultaneously, above-mentioned NMS comprises the function that the service supplier manages network.And, this NMS helping service supplier control and management consumer's IPTV receiver.If if use more IPTV receiver and more Additional Services are provided, then the effect of NMS just becomes more important.Therefore, snmp protocol becomes the mandatory agreement of IPTV radio receiver.This is intended to make the service supplier to manage and control the IPTV radio receiver.If like this, the IPTV radio receiver just can obtain the information of the processor of the details of the statistics of current communication protocol, current use, the information of TV manufacturer etc.
Fig. 4 is the block diagram of the system between service supplier and the radio receiver.
With reference to Fig. 4, service supplier's terminal can be carried out two-way communication via IP network.Specifically, according to native system, radio receiver can receive the information of broadcasting and can sending the environment of this radio receiver to the service supplier from the service supplier.
In this case, when the service supplier concentrates when radio receiver provides broadcast singal, broadcast stream and can comprise single or a plurality of programs.Transmit via IP network under the situation that transmits stream attempting, need carry out the IP encapsulation.
Fig. 5 is the figure that the IP encapsulation under the situation of service is provided to radio receiver via IP network the service supplier.
With reference to Fig. 5, the IP bag can comprise IP header, UDP header, RTP header and real data (that is transport stream packet).
Fig. 6 is the flow chart of method of the receiving adaptive broadcast signal of first embodiment of the invention.
With reference to Fig. 6, the method for the receiving adaptive broadcast signal of first embodiment of the invention may further comprise the steps: connect IP network; The codec information of being supported to service supplier's transmitter-receiver via the IP network that connects; The available service information tabulation that reception is provided based on the codec information of this receiver support by the service supplier, if and receiver selected at least a service from the tabulation of the available service information that received, then provide selected service to this receiver.
In IP network step of connecting (S61), terminal is connected with the service supplier via IP network.In this case, can preferably connect acquiescence service specified supplier.In the situation that several service suppliers are subscribed to, can select the concrete service supplier that will connect.
In the step (S62) of the codec information of supporting to service supplier's transmitter-receiver, the codec information of supporting is sent to the service supplier, to be provided the content of the codec encodes of supporting by this receiver.
In this case, be meant can be by the various forms of receiver decoding for the codec information of support.For example, ISO/IEC 11172 videos or ISO/IEC 14496-2 vision are supported video stream encoding and decoding device forms in receiver, and receiver sends to the service supplier with this codec information.
The step (S63) that receives the available service information tabulation from the service supplier, based on the codec information of the described support that sends to the service supplier, the service supplier will send to receiver by the content information tabulation of the various version of the codec encodes of this receiver support.For example, the service supplier sends the contents list of at least one version with this service supplier's outfit.For example, having received codec information ISO/IEC 11172 videos of support or the service supplier of ISO/IEC14496-2 vision sends by ISO/IEC 11172 videos or the tabulation of ISO/IEC 14496-2 content encoded to receiver.
In this case, be sent out too by the contents list of the codec encodes beyond the codec that radio receiver kept, so that the user can select.Alternatively, can only send tabulation by the content of the codec encodes that can be received device decoding.
Randomly, during the contents list of the codec encodes beyond similarly sending the codec that keeps by radio receiver, Downloadable codec list can be sent to receiver.
If the user has selected program (S64) at the receiver place, then this service supplier provides the content of being selected by the user (S65).If the content program of user's concrete version that selection will be watched from receive tabulation, then this service supplier provides corresponding service based on the selection signal of input.
In this case, at least one codec in the Downloadable codec list that user's download received, the content of the codec encodes beyond the codec that selection is kept by the receiver of prior art, and then provide selected content to the user by the service supplier.
If the user has selected the unsupported content of receiver, then the service supplier can send indication and should download the message that corresponding codec is watched content corresponding.In receiving the receiver of this download message, the corresponding codec of user's download or when downloading this corresponding codec, select selecteed content.
Fig. 7 is the detail drawing of method of the receiving adaptive broadcast signal of first embodiment of the invention.Describe broadcast signal received method between service supplier and the radio receiver in detail with reference to Fig. 7.In this case, Shuo Ming step only is exemplary in the following description, and claim of the present invention is not subjected to the restriction of following steps or its time order.
With reference to Fig. 7, when the service supplier provides broadcast service (1), the power supply of radio receiver be unlocked (1).
If the power supply of radio receiver is unlocked, then executive system initialization (2).
The radio receiver that has carried out system initialization is searched for attachable service supplier (3) or is proceeded to the service supplier's of default setting connection.Exist under a plurality of attachable service suppliers' the situation, then require the user to select.Like this, the user can select.
Serve when being connected with the service supplier in request, radio receiver sends its authentication information (3-1).
The service supplier who has received the authentication information of radio receiver carries out receiver authentication (4).
In case authenticated the qualification of radio receiver at authenticating step, then sent the relevant available information (4-1) of service with subscription.In this case, the available information relevant with the service of subscribing to is meant the available service information at receivable physical channel.
Radio receiver is carried out service discovery (5).This is search service and the step that determines service characteristic.By this step, radio receiver is connected to the service supplier.
Radio receiver shows services menu (6).Therefore, the user can see the available service about the service of subscribing to.
Radio receiver sends available resources (that is the codec information of support) (7) to the service supplier.
Receive after the codec information of described support that the service supplier compares (8) with the option of the various version of the content that keeps and the codec information of the described support that is received.Result as a comparison, the service supplier sends to radio receiver can be from the available service channel list (8-1) of this radio receiver output.Specifically, the service supplier sends available information at the receiver option.In this case, when sending by the coded contents list of the unsupported codec of radio receiver, the service supplier can send the tabulation of Downloadable codec simultaneously.
Receive the available service tabulation from the service supplier after, radio receiver shows this available service list (9).Then, the user selects at least a service (10) from available service list.In this case, the user selects the channel that will watch from available service tabulation, and the codec of selecting the content of same channel therefrom to export.In this case and the step (7) that sends the codec information of supporting at radio receiver send channel selective information together.Like this, the service supplier can provide available service release tabulation to selected channel.
In this case, if the user has selected from contents list by at least one coded content of the unsupported codec of radio receiver, then the service supplier sends the message that indication should be downloaded the codec that can support the respective streams exported.If radio receiver is downloaded this corresponding codec, then can provide selected content.
If selected programme information is sent to service supplier (10-1), the then selected service of service supplier's search subscriber (11) provides the service that searches (11-1) to radio receiver then.
Fig. 8 is the flow chart of the method for receiving adaptive broadcast signal second embodiment of the invention.
With reference to Fig. 8, the method for receiving adaptive broadcast signal second embodiment of the invention may further comprise the steps: connect IP network; Send codec information and the program selection information that radio receiver is supported via the IP network that connects to the service supplier; Come at providing at least a service in the available service information to radio receiver based on the codec information of the support that is sent by user-selected program.
The step that connects IP network is the same with first execution mode of the present invention with the step of the codec information that sends the radio receiver support to the service supplier.Yet, the difference of second execution mode and first execution mode is that the service supplier directly selects suitable codec version based on the codec information of the radio receiver support of receiving, provide by the coded content of corresponding codec to radio receiver then, rather than from the available service tabulation, select to offer user's service.
Sending codec information that radio receiver supports and program via the IP network that connects to the service supplier selects the step of information to comprise to the service supplier to send the step (S82) of the codec information that radio receiver supports and the step (S83) of the program that the selection user will watch.
Specifically, select information (that is channel information) to send to the service supplier codec information and the program supported.For example, the user has selected channel 10, and the codec information of supporting is provided simultaneously.
